- Product
- Microsoft Office Home and Business 2021
- Device & OS
- not provided
- Scenario
- Installing a newly purchased copy of Office Home and Business 2021 on a new computer.
- Observed behavior
- The installation process fails immediately, displaying a "Cannot verify signature" message alongside error code 30094-2016 (0).
Ensure you have uninstalled any pre-loaded Microsoft 365 trial versions or incomplete Office installations from your new computer using the Control Panel before attempting a fresh installation.
Install the 32-Bit Version of Office
Switching from the default 64-bit installer to the 32-bit version bypasses the signature verification conflict and allows the installation to complete successfully.
In some system environments, the 64-bit installer for Office 2021 struggles to verify its digital signature, triggering error 30094-2016. Using the 32-bit installer resolves this issue for most users and provides the same core functionality.
Go to the Microsoft account website and sign in. Navigate to the 'Services & subscriptions' page where your Office 2021 license is stored.
Locate Office Home and Business 2021 in your list of products and click the 'Install' button. When the popup window appears, do not click the main install button yet; instead, click on 'Other options'.
In the dropdown menu that specifies the version, change the selection from '64-bit' to '32-bit'.
Click 'Install' to download the 32-bit setup file. Once downloaded, run the executable file to complete your Office 2021 installation without the signature error.
Redeem the Product Key and Re-download
Ensure your product key is fully tied to your Microsoft account before attempting to download the software, as invalid setup files can cause signature errors.

Frequently Asked Questions
What does error code 30094-2016 mean during Office installation?
Error code 30094-2016 usually means the Office installer is struggling to verify the digital signature of the setup files. This can happen due to an unstable internet connection, corrupted download files, or specific system conflicts with the 64-bit installer version.
Will I lose features by installing the 32-bit version of Office 2021 instead of the 64-bit version?
No, the 32-bit version includes the exact same features and applications as the 64-bit version. The only difference is that the 64-bit version can utilize more memory, which is only necessary if you are working with extremely large Excel datasets (over 2GB) or massively complex project files.
Where do I find my Office 2021 product key if it is not on my receipt?
If you bought Office 2021 directly through the Microsoft Store, a physical key is not provided. The digital license is automatically tied to your Microsoft account. You can access and install it by logging into your account and navigating to the 'Services & subscriptions' page.
